Ray Kurzweil in 2006. Ray Kurzweil is an inventor and serial entrepreneur. When The Age of Spiritual Machines was published he had already started four companies: Kurzweil Computer Products, Inc. which created optical character recognition and image scanning technology to assist the blind, Kurzweil Music Systems, which developed music synthesizers with high quality emulation of real ...
Encoder receiver transmitter (ERT) is a packet radio protocol developed by Itron for automatic meter reading. [1] The technology is used to transmit data from utility meters over a short range so a utility vehicle can collect meter data without a worker physically inspecting each meter. The ERT protocol was first described in U.S. patent ...
Products include the Kurzweil 1000 text-to-speech converter software program, which enables a computer to read electronic and scanned text aloud to blind or visually impaired users, and the Kurzweil 3000 program, a multifaceted electronic learning system that helps with reading, writing, and study skills. Kurzweil sold KESI to Lernout & Hauspie ...
It operated in the 1,130 to 3,000 kHz frequency range with a transmission power of 30 Watts. It was used with various antenna ranging from 1.8 to 9-metre antenna. It was used for communication back to the regimental command post. Range 25 km AM voice to 140 km CW using the nine-metre antenna, the station had to be stopped to use this antenna.
An absorption wavemeter is a simple electronic instrument used to measure the frequency of radio waves. It is an older method of measuring frequency, widely used from the birth of radio in the early 20th century until the 1970s, when the development of inexpensive frequency counters, which have far greater accuracy, made it largely obsolete.
A radio band is a small frequency band (a contiguous section of the range of the radio spectrum) in which channels are usually used or set aside for the same purpose. To prevent interference and allow for efficient use of the radio spectrum, similar services are allocated in bands.
A radio repeater is a combination of a radio receiver and a radio transmitter that receives a signal and retransmits it, so that two-way radio signals can cover longer distances. A repeater sited at a high elevation can allow two mobile stations, otherwise out of line-of-sight propagation range of each other, to communicate. [ 1 ]
